Abstract: A method for directional distribution of allocation in two-way alternate line bundles which are switched between computer-assisted exchange facilities in voice and data networks. This traffic management method makes it possible to ensure full capability of a two-way alternate line bundle, while on the other hand, when traffic in one direction is temporarily dominant, traffic flow in the other direction is not impaired or displaced. A ratio for dividing the traffic in the outgoing and incoming directions is entered into the exchange facilities for the two-way alternate line bundle connecting them. The division ratio depends on the normal traffic flow in the outgoing and incoming directions. The allocation and direction of allocation of each line of the line bundle are constantly monitored by each of the two exchange facilities. As long as more than one line of the bundle is free, both exchange facilities can access the lines as required by the incoming connections. If only one line is free, the actual division ratio is considered and adapted to the theoretical division ratio.

Abstract: On produit un renforcement de structure (32) dans des environnements très humides en appliquant des couches de renfort comprenant une partie en tissu (34) et une partie en résine non durcie (36) contenant une résine de polyéther modifiée au silicone, durcissant à l'humidité. La couche de renfort non durcie durcit sur place sur la structure pour former une couche de renforcement composite (32). La couche de renforcement non durcie est formée à partir d'un textile tissé à sec ou d'un textile tissé qui est préalablement imprégné d'une résine durcie puis enduit d'une résine de polyéther modifiée au silicone, durcissant à l'humidité. Les structures selon l'invention sont particulièrement utiles pour le renforcement d'appuis et de pieux qui sont au moins partiellement immergés dans l'eau. Des couches de retenue sont utilisées pour empêcher la délamination pendant le durcissement de la structure de renforcement. L'utilisation d'une couche de retenue empêche non seulement la délamination due aux vagues ou à d'autres phénomènes de turbulence de l'eau mais accentue le processus de durcissement sous l'eau.

Abstract: A cryogenic liquid transfer system, for servicing a use device, releases stored cryogen from a bulk storage tank to a gas supply tank and a dispenser tank. The liquid cryogen in the gas supply tank is circulated through a circuit that includes a heat exchanger and the gas thus generated is returned to the gas supply tank so as to pressurize it. The pressurized liquid cryogen is released from the gas supply tank so that it flows through a vaporizer. The gas produced by the vaporizer is bubbled through the liquid cryogen in the dispenser tank so as to raise its temperature and pressure to the level required by the use device being serviced. Gas from the vaporizer is then delivered to the space above the liquid cryogen in the dispenser tank to as to create a pressure head that will cause the liquid cryogen to flow to the use device upon release. A venturi is connected to the tubing between the gas supply tank and the dispenser tank and is used to reduce the pressure in the bulk storage tank.
